Dyson's answer to Roomba...

Dyson's answer to Roomba...  Dyson's vacuum cleaners are awesome – we've owned two so far, and nothing else we've tried even comes close.  Not long ago, they announced that they'll soon have a competitor to Roomba, the robotic vacuum cleaner.  Only – because it's Dyson – it will, like, actually work.  I've no idea what they're going to sell for, but given the technology involved I suspect it will be at a considerable premium over Roomba.  With three floors in our house, we'd have to have three of the things, unless Dyson also figured out a way for it to climb up and down stairs.  Needing three would probably put it out of our price range.  But I can still admire the technology...
